ABSTRACT:
A data processing system with an apparatus for reducing loop processing time including an address reset circuit that resets the program counter and prefetch counter to the loop beginning address when the program executes the instruction at the loop ending address. The need for repeated address calculation for branching to a loop beginning address after each loop execution cycle is eliminated, thereby speeding up the loop processing.
